LLM Data Visualization Integration Workflow

A source-backed proof page for connecting LLM workflows to structured data visualization outputs, shown as repository-code proof with no unsupported runtime claim.

LLM data visualization proof visual with model node, structured table, Vega chart, and validation trace

This example demonstrates the LLM/data-visualization integration class: a model-facing interface, a structured data contract, and a chart output that can be inspected before it enters a business workflow.

Proof assets and links

repo-code-proof: docs/spec.md lists mcp-server-vegalite as a public technical candidate for LLM data visualization; no live deployment is claimed here.

Repository or technical proof boundary. Portfolio proof, not measured client metrics.

Problem

Teams want AI-assisted analytics interfaces that can turn questions and structured data into reliable visual outputs without hiding the data contract.

Context

The proof inventory lists mcp-server-vegalite as a public technical candidate for LLM-connected data visualization. This page packages that direction as an integration proof boundary, not as a separate MCP commercial service and not as a measured production result.

Inputs

Structured business data or chart-ready records
A chart request, prompt, or visualization intent

Technical approach

The workflow class connects an LLM-facing integration layer to a data visualization output such as a Vega-Lite chart specification. The important reusable pattern is the contract between prompt, structured data, generated chart specification, and reviewable output.

Stack

TypeScript / Node.js integration layer
LLM-facing tool or server interface
Vega-Lite-style chart specification

What was built

A source-backed integration proof class for turning structured data and LLM requests into reviewable visualization outputs, with a strict boundary that the public site is not claiming a live production analytics product.
